Guidelines Summary

The American College of Radiology (ACR) Appropriate Criteria® for imaging of acute trauma of the knee recommend plain radiographs for initial imaging of a fall or acute trauma to the need in patients older than 5 years with inability to bear weight. Recommended studies following evidence of tibial plateau fracture on radiographs and suspicion of additional bone or soft-tissue injuries are MRI without IV contrast or CT without IV contrast.  The ACR considers these modalities equivalent and only one procedure is needed. [23]

For patients with major knee trauma, such as dislocation, knee radiographs and CTA of the lower extremity with IV contrast is recommended for the initial imaging. These procedures may be ordered simultaneously when unique clinical information is expected from the results. The ACR found insufficent evidence to reach agreement on the appropriateness of knee CT with IV contrast as an initial imaging study. MRA with contrast and MRI without contrast may be appropriate for the evaluation of internal derangement and vascular injuries. [23]
